In this paper, we propose a sparse tensor additive regression (STAR) that models a scalar response as a flexible nonparametric function of tensor covariates. The proposed model effectively exploits the sparse and low-rank structures in the tensor additive regression. We formulate the parameter ...

4 Each atom of Ψ is then the tensor product of an atomic spectrum ξi and a spatial elementary signal ϕj: (17)∀ij∈1…n×1…T,ψij=ξi⊗ϕj. Recall that most popular sparse recovery results in the monochannel setting rely on the mutual coherence of the dictionary. In the...

Preprocessing of ultrasound data is necessary for integration into an input matrix or tensor in a special shape when applying DLSM algorithms. In general, the input of the DLSM algorithm consists of a sequence ofnconsecutive ultrasound data (F1…Fn) with the original size ofF∈Ri1×i2. For ...
The classic (ridge regression) solution for a smoothing spline is a special case of the proposed kernel eigenvector smoothing and selection operator. Extensions for tensor product smoothers are developed for both the GAM and SSANOVA frameworks. Using simulated and real data examples, I demonstrate ...
